3-32 Basic Installation MN1902If switches 1-4 are all in the Off position, the Mint NODE keyword can be used to set the nodenumber. WorkBench v5 (see section 5.2) reads the FlexDriveII node number (during the scanprocess) and then uses it to direct commands to the FlexDriveII.Avoid accidentally setting switches 1-4 to the On position at the same time. In combinationwith DIP switch 8, this will reset the FlexDriveII to its factory defaults. See section 3.9.7.3.9.2 Switch 5 - HoldSwitch 5 stops the motor. In the Off position, normal operation is allowed. When switched tothe On position, the motor decelerates to rest and maintains position. The switch position issampled every 100ms.3.9.3 Switch 6 - RS485 terminatorSwitch 6 is used to connect a termination resistor to the RS485 network. In the Off position,the RS485 network is unterminated at the FlexDriveII. In the On position, an internal 120Ωtermination resistor is connected between the RX+ and RX- signals - see section 4.4.5.Switch 6 should remain in the Off position when using RS232.3.9.4 Switch 7 - Offset tuningSwitch 7 is used to start offset tuning on analog (command) input AIN0. The purpose of offsettuning is to remove DC offset voltages on analog input 0 (the command reference input) toachieve a stationary motor shaft with 0VDC at the input. Confirm that the device supplying theAIN0 command input is set to its intended zero output setting (nominally 0VDC) before startingoffset tuning. When switch 7 is in the On position, offset tuning will start the next time Enable(switch 8) is changed from On to Off.On7Wait for 1 secondfor offset tuningto be completed.Off 71. 2. 3. 4.Off 8On8Figure 19 - Offset tuning using switch 7 and 8Leave switch 7 Off in normal use. After offset tuning, remember to set switch 8 to the Onposition to allow the drive to be enabled. The switch positions are sampled every 100ms. TheMint keyword ADCOFFSETTRIM can be used to perform the same action.3.9.5 Switch 8 - EnableSwitch 8 must be set to On to allow the drive to be enabled. The switch position is sampledevery 100ms. However, two other actions are necessary to enable the FlexDriveII:H The enable input (see section 3.8) must be active.H The drive must also be enabled by using a drive enable command (see section 3.8.3).
